Factors That Influence Stem-Promising Females’ Decision To Attend A Non Research-Intensive Undergraduate Institution, Roxanne Greitz Miller, Ashley J. Hurlock
Education Faculty Articles and Research
Non research-intensive institutions of higher education are effective at narrowing STEM gender gaps in major selection and persistence to degree completion, yet the decision to attend such a setting is likely seen as counterintuitive when such institutions typically have lower levels of research, financial resources, and total student enrollments in the sciences. This case study identifies institutional factors reported by ‘STEM-Promising’ females, defined as females who completed at least one Advanced Placement (A.P.) STEM course in high school, as influencing their decision to attend their non research-intensive undergraduate institution. Using a quantitative, crosssectional research design and original survey, 23 out …

Mathematics Discourse And Its Relationship To The Development Of Collective And Individual Student Knowledge In The Context Of Limits, Patterson Rogers
Legacy Theses & Dissertations (2009 - 2024)
Observing a group discussion, it is not possible to infer an individual student’s understanding from the dialogue. When students discuss, they share their individual ideas to develop a collective understanding which in turn informs students’ individual understanding. Clarifying the relationship between collective and individual understanding provides insight into how individuals construct mathematical thinking. This study presented an embedded case study to answer three questions regarding the role discourse plays in student development of mathematical knowledge: (1) how individual students construct mathematical knowledge through discourse, (2) the nature of discourse which supports the development of mathematical knowledge, and (3) the relationship …

Stem Outreach Efforts For Urban Students, Otilia Popescu, Vukica M. Jovanovic, Jennifer G. Michaeli, Stacie Ringleb, Alok Verma
Engineering Technology Faculty Publications
Four-year universities and community colleges rely on outreach efforts to bring the awareness of STEM-related careers to students, who might be interested in joining their student body in the future. These events are of utmost importance for students, who do not have all of the necessary role models to engage them in conversation about their future careers. Some students might not perceive a STEM career as valuable and feasible in their future career paths, even if their own schools offer information and resources related to STEM career pathways. Hence, various outreach efforts at different levels of education have to be …

Engineering Technology Faculty Publications
Writing to learn is one of the very important pedagogical strategies in a variety of disciplines. This concept is not specifically addressed in the majority of engineering courses. Hence, university initiatives such as the Quality Enhancement Plan (QEP), emerging out of accreditation and institutional assessments, are focusing on infusing scholarship from other disciplines (in this case English) for the purpose of student learning improvement. Engineering and Science programs do include various courses in English Composition as the part of the curriculum; however, writing is not embedded in all discipline-specific courses at the upper-division level. The program outlined here focuses on …

The Changing Roles Of Science Specialists During A Capacity Building Program For Primary School Science, Sandra Herbert, Lihua Xu, Leissa Kelly
Australian Journal of Teacher Education
Science education starts at primary school. Yet, recent research shows primary school teachers lack confidence and competence in teaching science (Prinsley & Johnston, 2015). A Victorian state government science specialist initiative responded to this concern by providing professional learning programs to schools across Victoria. Drawing on cultural historical activity theory (CHAT), this paper reports the analysis of transcripts of interviews with 17 science specialists from eleven schools. It presents the various perceived and enacted science specialist roles, and how they changed over time. The CHAT analysis of the transcripts revealed seven different stages describing trajectories of the science specialism. The …
